Abstract: Disclosed are a system message notification and sending method and apparatus. The method comprises: a CU determines system message relevant information; and the CU sends the system message relevant information to a DU. The DU receives the system message relevant information sent by the CU; and the DU notifies a terminal of the information. The present application provides an access control and system message processing solution under a CU-DU architecture, and a CU can provide sufficient auxiliary information to a DU, and thus the DU can generate suitable system information according to same. The two coordinate to provide a service to a UE, and the system efficiency is improved and a good user experience is ensured.

Abstract: Provided in embodiments of the present disclosure a QoS processing method and a QoS processing device. The QoS processing method includes transmitting, by a target base station, a first message to a source base station. The first message at least comprises first information and second information; the first information is configured for notifying the source base station that the target base station is incapable of meeting a QoS requirement on one or more flows of a UE; and the second information is information of a QoS parameter capable of being accepted by the target base station and recommended with respect to the one or more flows.

Abstract: A method for transmitting a radio resource control message, a network side central unit, and a network side distributed unit are provided. The method for transmitting a radio resource control (RRC) message includes: mapping the radio resource control (RRC) message into a data stream of a level corresponding to a user plane; and sending effective time and a logical channel identifier of the RRC message and the data stream to a corresponding network side distributed unit (DU) through the user plane or a control plane.

Abstract: Provided in an embodiment of the present invention are a method and user equipment (UE) for reestablishing an RRC connection. The method of the embodiment of the present invention includes a UE having experienced a connection failure initiates a request for reestablishing an RRC connection in a selected reestablishment cell, and when determining that the reestablishment cell does not meet a preset cell selection criterion or the UE did not receive an RRC connection reestablishment command transmitted by the network side device that the reestablishment cell belongs to, the UE determines not to carry, in the information related to the connection failure and stored by the UE, the identifier information of the reestablishment cell, or not to store any information related to the connection failure.

Abstract: Embodiments of the present application discloses a method, system and apparatus for transmitting Minimization of Drive-Tests (MDT) measurement configuration parameters, relate to the field of wireless communications and address the problem that a User Equipment (UE) can not perform MDT measurement when the UE is configured by the network side to perform MDT measurement. In the present application, a Mobility Management Entity (MME) receives MDT measurement configuration parameters of a user equipment transmitted from a Home Subscriber Server (HSS); the MME determines whether cell list information in the MDT measurement configuration parameters includes information of a cell controlled by a base station controlling a serving cell of the user equipment; and the MME transmits the MDT measurement configuration parameters to the base station serving the user equipment when the result of determination is YES. With the invention, the problem of the UE failing to perform MDT measurement can be avoided.

Abstract: Disclosed are a terminal control method and device, used for implementing control on a user equipment (UE) with a proximity perception capability when a D2D communication mechanism for mutual discovery even direct communication between mobile devices is introduced to a network. The method is: an MME receiving a D2D request message of a UE that is sent by a base station, determining requested D2D characteristics according to the D2D request message, determining an acceptable D2D characteristic in the requested D2D characteristics, and sending the accepted D2D characteristic to the base station; and after receiving the accepted D2D characteristic returned by the MME, the base station determining whether to accept the D2D request of the UE, and if yes, the base station performing resource configuration and instructing the UE to perform the accepted D2D characteristic; otherwise, the base station rejecting the D2D request of the UE.

Abstract: Disclosed are a method and device for performing MDT measurement configuration. The method includes: after receiving a notification of a change of subscription information about a user equipment, an MME storing a PLMN list for the user equipment to perform MDT measurement carried in the notification; and after receiving a notification for activating MDT measurement of the user equipment, the MME sending a trace start message to a serving base station of the user equipment, wherein the trace start message carries the PLMN list for the user equipment to perform MDT measurement.

Abstract: Provided in an embodiment of the present invention are a method and user equipment (UE) for reestablishing an RRC connection, used to solve the problem in the prior art of conducting incorrect optimization of handover parameters by a network side when a UE, having experienced a connection failure, reestablishes an RRC connection in a cell but the cell does not meet a preset cell selection criterion or the UE did not receive an RRC connection reestablishment command transmitted by the network side.
